False. Electromagnetic and Gravitational forces can overcome .
Answer:
Conduction
Explanation:
Conduction is the transfer of heat energy from one substance to another or within a substance.
Answer:
Acid-base
Explanation:
KOH is a strong base, and NH₄Cl is an acid. They react to form a salt and water.
KOH + NH₄Cl ⟶ NH₃ + KCl + H₂O
base acid salt water
Answer:
A) solute - NaCl, solvent - water
B) solute - O2 and other gases, solvent - N2
C) solute - ethanol, solvent - water
D) solute - tin, solvent - copper
Explanation:
Solute(s) is/are the minor component(s) in a solution, dissolved in the solvent.
Solvent is the component of a solution that is present in the greatest amount. It is the substance in which the solute is dissolved.
If both solute and solvent exist in equal quantities (such as in a 50% ethanol, 50% water solution), the concepts of "solute" and "solvent" become less relevant, but the substance that is more often used as a solvent is normally designated as the solvent (in this example, water).
Answer:
See below
Explanation:
The equation shows Al / Cl = 2/3 or 3/2 Al = Cl
3/2(20) = 30 Cl atoms needed
The equation shows a one-to-one relationship between Al and AlCl3
produced so if you use 20 Al atoms you get 20 AlCl3 molecules
